California Science — Grade 4
Comprehensive Course Syllabus
Course Overview
Our California Grade 4 Science course is designed around the California Next Generation Science Standards (CA NGSS). Students explore life science, physical science, earth and space science, and engineering through investigations, models, evidence-based explanations, and design challenges.
Grade 4 places particular emphasis on plant and animal structures, sensory information, energy, waves, electricity, energy transfer, rocks and fossils, Earth’s changing landscapes, and engineering solutions. Students learn science through investigation and evidence rather than memorization alone.
Plant & Animal Structures
Plant Structures
Students explore structures such as roots, stems, leaves, flowers, and thorns and investigate how these structures support plant growth, survival, and reproduction.
Animal Structures
Students investigate major external and internal structures of animals and understand how different structures support survival, growth, behavior, and reproduction.
Structure & Function
Students connect the structure of a plant or animal part with the specific function it performs within the organism.
Systems in Living Organisms
Students learn that living organisms contain interacting parts and use simple models to understand how different structures work together.
Senses, Information & Animal Responses
The Five Senses
Students explore how animals receive information from their surroundings through specialized senses such as sight, hearing, smell, taste, and touch.
Sensory Information
Students investigate how different sensory organs receive different types of information from the environment.
The Brain & Information Processing
Students learn at an age-appropriate level how sensory information is processed by the brain and used to guide responses.
Animal Responses
Students explore how animals respond differently to information from their surroundings and use models to represent these information pathways.
Systems & Interactions
Students investigate how different parts of an animal’s information-processing system work together to receive information and produce responses.
Energy & Motion
Energy & Moving Objects
Students investigate the relationship between the speed of an object and its energy and use observations as evidence for scientific explanations.
Energy Transfer
Students explore how energy can move from one place to another through moving objects, sound, light, heat, and electric currents.
Collisions & Energy
Students investigate what happens when objects collide and observe how energy can be transferred between objects, changing their motion.
Energy in Everyday Life
Students identify examples of energy being transferred or transformed in familiar situations involving movement, sound, light, heat, and electricity.
Predicting Energy Changes
Students ask questions and make predictions about how energy may change when objects interact or collide.
Electricity & Energy Conversion
Electric Currents
Students explore how electric currents can transfer energy and produce effects such as light, heat, sound, or motion.
Energy Transformations
Students investigate how energy can change from one form to another in everyday devices and simple systems.
Electric Devices
Students explore examples of devices that use electrical energy to produce light, sound, heat, or motion.
Designing Energy Devices
Students apply scientific ideas to design simple devices that convert energy from one form to another.
Testing & Improving Designs
Students test their energy-conversion designs, observe how well they work, and make improvements based on evidence and identified constraints.
Waves, Sound & Information
Understanding Waves
Students explore waves as repeating patterns of motion and use simple models to represent how waves move.
Amplitude & Wavelength
Students identify basic wave characteristics such as amplitude and wavelength and recognize patterns in different waves.
Waves & Object Movement
Students investigate how waves can cause objects to move and use observations to describe these interactions.
Sound as Energy Transfer
Students explore sound as a form of energy transfer and investigate how vibrations and waves can carry information.
Waves & Communication
Students explore how patterns in waves can be used to communicate information and connect science concepts with everyday technologies.
Rocks, Fossils & Changing Earth
Rocks & Earth’s History
Students examine rocks as evidence that Earth’s surface has changed over long periods of time.
Fossils in Rock Layers
Students investigate fossils found in different rock layers and use their positions and patterns as evidence about Earth’s past.
Reading Rock-Layer Evidence
Students compare patterns in rock formations and fossils to develop explanations about how landscapes have changed over time.
Changing Landscapes
Students explore evidence that areas can change from land to water or water to land over long periods of time.
Earth Forces & Landscape Change
Students investigate how Earth processes, including earthquakes, can contribute to changes in landscapes and rock formations.
Scientific Investigation & Engineering Design
Asking Scientific Questions
Students learn to ask questions about observable phenomena and identify questions that can be investigated using evidence.
Planning Investigations
Students plan simple investigations, make observations, collect data, and use evidence to answer scientific questions.
Developing Scientific Models
Students create and use models to represent living systems, sensory information, waves, energy transfer, and changes in Earth’s surface.
Defining Engineering Problems
Students identify engineering problems, desired outcomes, available materials, limitations, and criteria for determining whether a solution works.
Designing & Testing Solutions
Students develop possible solutions, test their designs, compare results, and identify ways to improve them.
Evidence-Based Scientific Communication
Students use observations, measurements, models, and evidence to explain scientific ideas and communicate their findings clearly.
Teaching Methodology
Our Grade 4 Science classes focus on scientific investigation, evidence-based reasoning, modeling, experimentation, and engineering design.
